What terminal does Delta use at Heathrow?

What You Need to Know. Delta Air Lines now operates in Terminal 3 at London Heathrow International airport (LHR). All passengers with London as a destination must collect their bags after clearing immigration and then proceed through customs.



As of 2026, Delta Air Lines operates out of Terminal 3 at London Heathrow (LHR). This terminal serves as the primary hub for Delta and its joint-venture partner, Virgin Atlantic, allowing for seamless connections between the two airlines. If you are arriving at Heathrow to check in for a Delta flight, you should head to Zone A in Terminal 3, which is the dedicated area for Delta and Virgin Atlantic check-in and bag drop. One of the major benefits of using Terminal 3 is the access to high-quality lounges; eligible Delta passengers can utilize the Virgin Atlantic Clubhouse or the American Express Centurion Lounge. If you are connecting from a Delta flight to an onward flight with SkyTeam partners like KLM or Air France, be aware that those carriers typically operate from Terminal 4, which requires a short, free train or bus transfer from Terminal 3.
